Shure BLX14/PGA31 Wireless Cardioid Headset Microphone System (H10: 542 to 572 MHz)

The Shure BLX14/P31-H10 is a headset microphone package that operates wirelessly and lets you present, teach, or perform without holding a mic. Built on Shure’s BLX platform, it provides dependable transmission and straightforward setup in classrooms, houses of worship, fitness studios, and small stages.

At the center of the system is the PGA31 headset. The frame stays securely in place while remaining unobtrusive, and a flexible gooseneck helps you position the cardioid condenser capsule exactly where it captures your voice best. This polar pattern focuses on your speech and reduces room noise and feedback, so listeners hear your message clearly.

Audio travels from the headset through the BLX1 bodypack transmitter on the UHF H10 band between 542 and 572 MHz. A single press of the QuickScan button on the BLX4 tabletop receiver searches 123 available channels and locks in a clean frequency, a real time-saver when other wireless gear is active nearby.

Two standard AA batteries power the bodypack for up to fourteen hours, supporting long rehearsals, day-long seminars, or multi-set gigs. A line-of-sight range of up to three hundred feet lets you move across large stages or gym floors without worrying about dropouts.

Connecting the BLX4 receiver is easy. Balanced XLR and unbalanced 1/4 inch outputs allow direct hookup to a mixer, powered speaker, or audio interface. If your production grows, you can run as many as twelve BLX systems in the same frequency band without conflict.

Whether you lead fitness classes, deliver corporate training, act in community theater, or front a small band, the BLX14/P31-H10 is a reliable partner that keeps the focus on your performance, not the equipment.
